She will play Mary Louise Wright, the mother of Perry White (Alexander Skarsgard) in the upcoming season.

Nicole Kidman, who plays Celeste - the wife of Perry, shared a first look image of Streep in character on set.

Alongside the photo she wrote: “First day on the set with Meryl and “my” darling boys! #BigLittleLies”

According to Deadline here’s a synopsis of Streep's plotline: "Concerned for the well-being of her grandchildren following her son Perry’s death, Mary Louise arrives in Monterey searching for answers."

HBO describes the second season as "darkly comedic drama Big Little Lies will explore the malignancy of lies, the durability of friendships, the fragility of marriage and, of course, the vicious ferocity of sound parenting. Relationships will fray, loyalties will erode, and the potential for emotional and bodily injury shall loom."
